Exact Matching-Polynomial Solution of the Periodic Baxter-Fendley $Z_{N}$ Clock Chain

Yuguan Li, D. C. Liu, Murray T. Batchelor

The periodic non-Hermitian Baxter-Fendley $Z_{N}$ clock chain has lacked a complete finite-size spectral solution, whereas its open-chain counterpart admits a solution in terms of in…

Exceptional point rings and $P T$ -symmetry in the non-Hermitian XY model

Robert A. Henry, D. C. Liu, Murray T. Batchelor

The XY spin chain is a paradigmatic example of a model solved by free fermions, in which the energy eigenspectrum is built from combinations of quasi-energies. In this article we s…
